Overview of Boiler, Cooling Tower & Process Water Testing

Tested by: NABL-accredited partner lab
Regulation: IS 10392 & ISO 11731
Typical turnaround: 3–7 working days
Sample needed: 1–2 litres per point

Poor water chemistry is behind most boiler tube failures and cooling system breakdowns. IS 10392 sets the requirements for boiler feed water and boiler water by operating pressure, and boiler inspections under the Indian Boiler Regulations look at water treatment. Hardness, silica, dissolved oxygen, pH, conductivity and iron show whether the treatment programme is working.

Cooling towers concentrate minerals as water evaporates and can grow Legionella, the bacteria that cause Legionnaires’ disease when contaminated mist is inhaled. Testing combines chemistry, scaling and corrosion indices, total bacterial counts and Legionella culture to ISO 11731. RO and DM plants are checked for the quality of the water they produce. For water that people drink, see drinking water testing.

How we handle Boiler, Cooling Tower & Process Water Testing

1
Assessment of requirement
We confirm the standard, the list of tests and how many samples your product needs.
2
Sample collection
We collect the samples from your factory or warehouse, or tell you exactly where to send them.
3
Right lab assigned
We choose an accredited lab (NABL, BIS-recognised or ILAC) that covers your standard and can start soonest.
4
Testing
The lab tests your samples against the standard. We follow up and tell you at once if a test fails.
5
Test report
You receive the signed test report, ready to use for BIS, WPC, CE or your buyer.

What the lab tests

Parameter	Why it is checked
Hardness, alkalinity and pH	Scale formation and treatment control
Silica and conductivity	Carryover and blowdown control
Iron and copper	Corrosion in the system
Scaling indices (LSI, RSI)	Tendency to scale or corrode
Total bacterial count	Biofouling in cooling water
Legionella (ISO 11731)	Health risk from cooling towers

The final list depends on your product, its standard and the purpose of testing. We confirm it with you before the sample goes to the lab.

Frequently asked questions

How often should cooling towers be tested for Legionella?

India has no statutory frequency. Hospitals, hotels and many multinational sites test quarterly as a matter of policy, and more often after a positive result or when the system has been shut down.

Will auditors and inspectors accept the report?

Monitoring is done by NABL-accredited labs using recognised Indian and international methods, which factory inspectors, green building assessors and customer auditors accept. Where your state rules name specific agencies, we check this before booking.

Who carries out the testing?

Instacertify’s partner laboratories, accredited by NABL to ISO/IEC 17025 for the parameters on your report. We choose the lab, arrange the sample, follow up until the report is issued and explain the results to you.
